The TL-LD1100 is great, I just replaced my last Mars 3.0 with it (Mars was bright, but after breaking/losing my 3rd one I was done with them). I keep a superflash as a backup light.
While the superflash might blind you a little more when it's in your hand, the sheer size of the 1100 helps it to be better in my experience. This goes triple when it's wet out.
Better yet, get one of each and put them at different heights. I have been running just the 1100 in light to moderate traffic, adding the superflash to my backpack when desired.
